I was so lucky that Eric was assigned as my plumber. His professionalism was evident when he introduced himself and put on those “booties” as not to dirty my floors. I had a leak that we didn’t know the source. Eric asked questions and listened to my ideas and didn’t laugh lol. He worked tirelessly to diagnosis the source without doing too much damage to the floor/walls etc. When he found the source of the leak, he showed me and explained what needed to be done. Most important, he gave me options knowing that cost was important. He went above and beyond my expectations. Eric is a first-class plumber, as well as a first-class person that I can trust in my home. Ask for Eric you will be glad you did!

The winter of 2025-2026 was pretty brutal, with temps in single digits on some days. I had shut off our first floor baseboard heating due to a leak somewhere in the water pipe system. However the old Levitt house we live in have the pipes embedded into the concrete slab (no basement) so finding the leak was especially challenging. Our HVAC system plus the Dyson Heating unit DID NOT provide enough heat during the cold nights. In March we finally called several plumbing contractors to see how the leak can be detected and repaired. Only Chivalry offered using thermal imaging gun to try to narrow where the leak might be. Eric and Rich came out to perform the scan and identified two possible leak locations. The first potential leak site was in the kitchen. They were able to limit removing just a single 18×18-inch tile to access the pipe, but this location showed no leak. The second location, near the back door, required cutting through laminate flooring, and that is where they found the leaking pipe. Replacing the leaking pipe section was fairly standard. But the hardest part was finding the leak. We are grateful for Eric and Rich's detective work and the repair done to restore our baseboard heating. Now we can look forward to a warm winter next year. PS. Its up to the homeowner to repair the surface AFTER the digging, which I was able to do myself. Luckily, I kept some tiles and floorboards.

I’ve been meaning to write this for a while. Back in Fall 2025, Chivalry Plumbing installed our new boiler and removed the old one, and the whole experience was excellent from start to finish. Will, Anthony, and Eric were fantastic to work with. They were professional, respectful of our home, and incredibly clean and neat throughout the entire process. What really stood out was how efficiently they worked. They completed a full boiler installation and removal in just one day, and the setup they put in is top notch. We couldn’t be happier with the quality of the work. I highly recommend Chivalry Plumbing to anyone looking for reliable, skilled, and courteous service.
